SEPARABLE PJM.

Application filed March 18, 1915.

To all 'whom t may concern 'Be it known that I, Pn'rnn S. LARSON, a citizen of the United States, residing at Beloit, in the countyv of Hock and State of llfisconsiii, have invented certain new and useful Improvements in Separable Rims; andl` do declare the following to be a full, clear, and exact description of the invention," such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in separable rims adapted for use in connecA- tion with vehicle wheels equipped with tires of the pneumatic type.

The primary object of the invention is to provide a sectional rim by means of which the positioning or removing of a pneumatic tire will be greatly facilitated and which may be used leither in connection with i straight tire or with a tire of the clencher type.

Another object of the invention is to provide a rim of this character which while simple and economical in construction is very light and strong and is so positioned and held on the felly of a wheel that no skidding or sliding sidewi'se of the rim can take place.

Another object is to so construct a rim of this character that it will reinforce and strengthen the felly of the wheel to which it is applied and at the same time greatlyfacilitate the removal and replacement of a tire when necessary.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure l is a side elevation of a wheel equipped with this improved rim; Fig. i2 is an edge view of the rim detached with the parts arranged in juxtaposition ready for assembling; Fig. 3 is a transverse section taken on the line 3 3 of Fig. 1 showing the rim' applied to a clencher tire; Fig. el is a side portion of a wheel equipped with this im proved rim with one of the members of said rim removed Showing the device ready for slipping off the tire; Fig. 5 is an edge view showing the parts in juxtaposition ready for.

- assembling when the device has been used Specification of Letters Patent.

in connection with a straight-walled tire, and Fig. G is a transverse sectionthrough the wheel anditire.

1n the embodiment illustrated a wheel l is shown provided with a wooden felly 2 to which the spokes 3 are attached in the usual On the opposite side faces of this folly 2 adjacent the inner portion thereof are arranged two annular shoulders 4 andV 5 which are designed to form seats for receiving the rim constituting this invention and also to afford stops for `limiting the inward movement of said rim when applied.

The rim constituting this invention comprises a section A comprising an annular band G of a width corresponding substantially to the peripheral portion of the fell y 2 between the shoulders Il and 5 thereof. This band (l is provided on one edge with an inwardly extending radial lange 7 of a width corresponding to the distance between the periphery ofthe felly 2 and the outer face or periphery of one ofthe shoulders thereof so that when said section is applied to the fellj7 this band will rest on its pe riphery with the inner edge of the flange 7 seated on the shoulder 5, as is shown clearly in Fig.` 3, the outer face of said flange extending flush with the outer face of said shoulder.

Projecting beyond the band 6 substantially in alinenient with the flange 7 is a peripheral flange 8 here shown constructed in accordance with the well known clencher type of rim having an inturned hook 9 to receive the bead projection carried by a clencher tire. The other section B of this improved rim comprises an annular plate 10 of a width corresponding to the width of the flange 7 of the other section and which isV adapted to be disposed on the side of the felly opposite to that on which the flange '7 is disposedfwhen the parts are assembled,

and to be seated with its lower edge in engagement with the.shoulder 4: formed on said felly, the outer face of said plate being arranged flush with the outer face of said shoulder. rlphis plate 10 is provided at its peripheral edge'with a hook-like radially extending flange 11 which projects beyond the periphery of the felly and the band 6 of the other section beingof alengthcorresponding to the length of the flange 8 of said other section and adapted to coperatie therewith for securing a tire in yposition be! tween them. This plate 10 is reversible to adapt the rim to be used either in connection with a tire of the clencher type or with a straight tire. When it is used in connection with a straight tire the hook-shaped flange 11 thereof is disposed outwardly as shown inFigs. 5 and 6 and a filling member 12 is shown mounted in the recess in the inner face ofthe flange 8 of the other section, thus presenting two straight flat opposed walls between which a stra-ight pneumatic tire is designed to be mounted. When this rim is to be used for securing a. tire of the clencher type, the hook l1 is disposed inwardly and the`annular member 12 is removed from the rim as ,shown in Figs. 2 and 3 and the tire: may then be readily l clamped betweengthe hooks 9 and 11 of said 20 rim which engagebeads on the opposite sides'Tof-.jthe tire, as'shown in Fig. 2. These rim sections A and B are 'secured to the felly 2 by a plurality of, bolts 13 which eX- tend transversely through the flanges 7 and 10 of the sections and through said felly and are secured in operative position by the usual nuts 14. While eight of these bolts arfh'erein' shown spaced equal distances apglart,'it is obvious that any desired number ,may be employed, and when said sectidns are so disposed and clamped they will be held reliably in engagement with the opposite side. faces of the felly 2 and thereby ,form not only rim securing means, but felly reinforcing plates.

In the practical use of this rim when a y tire becomes punctured or itis desired to remove one for anyother purpose,"all that is necessary is to loosen the nuts 14 and slide oli' the section B, leaving section A in position on the felly. The tire may then bc readily slipped off sidewise and readily repaired or replaced by a new one, andafter a new tire has been replaced, the section B is rengaged with the bolts 13 and the nuts .14 'are inserted on said bolts, thereby clamping the rim and tire in operative position on the wheel. rfhese bolts 14 are preferably spaced equal distances apart to facilitate the application of' the section B so that when one aperture in said section is engaged with one of the bolts, the other apertures therein will be automatically positioned -in engagement with the other bolts, thereby avoiding the necessity of locating the respective bolts with relation to certain apertures.

y One of the essential features of this ini vention is the facility with which a punctured tire may be removed and a new one inserted even by a novice, and the reversibility of the removable plate of the rim to provide for the use of the rim in connection with either straight or clencher tires.

The flanges 7 and 8 of the section A are shown made integrally with Athe band 6, thereby greatly strengthening and reinforcing both the top and one side of the felly and thus eliminating the danger of spokes being broken out resulting from split rims. The band 6 of-section A is provided with a transversely .extending slot 6 for the pas- -sage therethrough of .the inflation valve V carried by the pneumatic tire.

I claim as my invention: The combination with a felly, of a .sec-

tional rim on said fel-ly and comprising a section in the form of an annular band for engaging the periphery of said felly and of a width corresponding to. the width of said felly at its periphery, a radial flange eXtending inwardly from one edge of said band and adapted to contact with one side of the felly, and a peripheral flange extending radially beyond said band in alinement with said first mentioned flange and having an inturned edge to form a'semicircular. tire bead engaging member with the groove on its inner face, the other section 0I' said rim comprising an annular plate corresponding in width to the combined width of the fianges of said first mentioned section and having a semicircular fiange on its peripheral edge corresponding to the peripheral fiange of the Aother section, said plate being adapted .to have its inner portion contact with the oppositeside of the felly, bolts
